Hello Folks, My macbook pro is not booting. It stops at white screen with apple logo. I tried the sequence posted on apple's support website but am stalled at the step where it asks me to load from install disks. I have lost the install disks. So downloaded the SL10A432 user dvd image on a usb stick with transmac on a windows machine. When I try to boot with this build with "c" key on startup, the MBP appears to load from usb (lights flicker on the usb stick) and I see a progress bar. After sometime, the progress bar disappears and the spinning wheel appears again. I restarted this time with option key - and selected the usb drive. The startup manager correctly recognizes the usb stick as "MAC OS X Install DVD" I select to boot from it but then I get a popup message saying that I need to restart my computer. When I do, it stops on the same screen i.e. apple logo and spinning wheel. I would appreciate any insights and guidance. This is my first tryst with Mac+OS X. Have been a windows guy all my life. Thank you. Best regards.
